Product Description:

General Information:

CMAX brand Silica bricks are made from high quality quartz tail sand, lime and mineralizing agent through the process of crashing, screening, mixing, pressing, drying and sintering.

 

Features of Refractory silica bricks for Glass Kiln:

1. high volume density of 2.34 g/cm3

2. high SiO2 content of 96%

3. low iron content of 0.8%

4. low melting point of 5%

 

Applications of Refractory silica bricks for Glass Kiln:

Because of the high temperature resistant performance significantly, long service life characteristics (as long as more than eight years) of refractory silica brick for Glass Kiln, it can significantly improve the quality of glass, so the refractory silica bricks are widely used in all kinds of glass furnace melting department, regenerator and other important parts.

Q:The fire prevention board line is made of what material?
The line is a kind of composite stainless steel decorative profiles which outer layer is the matte frosted stainless steel plate and inner liningl is wooden material. It do not need to render with fine wood and also need not to buy a stainless steel plate cutting, cutting, bending, such as multi-channel intricate process, processing production. It is convenient to install through the buckle button directly on the booth. When installation, it only needs to be bolt and plug to be fixed on the wallafter blanking cut. compared with the traditional wooden play crural line, the profile is more beautiful and firm, and environmental friendly. And compared with the traditional craft production of stainless steel line, it's cheaper and more convenient to install. This product is not only sitable to decorate in the family, but also is more suitable for the hotel, hotel, office building, and the application of all kinds of public places.
Q:How long is the duration of fire resistance that fireproof window of level B can endure?
Fire proof window of level B is the fire proof window whose duration of fire resistance is not less than 1 hour.  Technical requirements: One, Materials and fittings (1) the frame of windows draw on steel or wood frames which have certain intensity and are able to ensure the integrity and stability of components.  (2) Steel frame and layering can use galvanized steel or stainless steel plate. Its selection criteria shall be in line with provisions 5.1 of GB12955< steel fire door general technical conditions >. (4) The internal fillings of steel, wood frames should use non combustible materials. (5) Fire proof windows can opt for qualified products without affecting the performance of fire proof window. Light transmittance of glass shall not be less than 75% of the same layer of ordinary flat glass.  (6)The sealing material between the frame and the fireproof glass should adopt the nonflammable materials, functioning as the fire blocker. (7)Hardware fittings should be tested for qualified products.
Q:What kinds of refractory materials that uses a-Al2o3 powder? What are the purpose of it?
04La-Al2O3 powder is a alumina powder whose raw material is industrial aluminum oxide which has been calcined at high temperature. It is a good polishes for ceramics and jade, meanwhile, it is also an important raw material for high-end refractory materials. The technical indicators parameters A1023 mark A1535 chemical composition AL2O3≥ 99.92 3%, ≥ 3.10FE203≤ 0.799 Refractory calcined alumina powder (a-Al2O3) 1.2 true density (g & # 47, by fully ground powder made of different fineness .O.10 0.07 0.04NA2O≤ 0.93a-Al2O3 (%) ≥ 95 95 primary crystallization average grain (um) 2 ~ 3 3 ~ 5 average particle size (um) 40 ~ 602.6SIO2≤ 0.1 0.15B2O3≤ - 0, glass, engineering ceramics typical use electronic ceramic insulating ceramic refractory ceramic wear 3
Q:How to calculate the thickness of choosing refractory? Such as steel ladle should choose what kind of refractory and using what thicknes?
The relative production is lower and material cost is higher, the lining of the refractory is thicker: 1, determine the weight of the refractory material according to the main structure of the bearing capacity, to prevent damage to equipment, fire-proof material damage after the surplus size and thickness of the thermal conductivity of refractory materials, the smaller the effective volume, production output, the cost of materials) to consider the selection of refractory material thickness. 3 from the point of usage (usage cycle, relative usage cycle is longer, because under the condition of invariable in the device's overall dimensions of the refractory lining thickness to determine several basic principles, according to the volume of the weight computation of refractories and refractory thickness, these items must be fully consider the pros and cons before decided. 2 according to maximum temperature that shell can withstand.
Q:What is the material of fire resistant glass reinforced plastics grating?
What is the material of fire resistant glass reinforced plastics grating?
Q:Which kind of furnace hearth refractory is better?
Coal is acidic medium, so the matched material should be acidic refractories oriented, like silica bricks. For example, the coking coke oven and carbon furnace made of carbon are in reducing atmosphere, so they use silica bricks which have low price and good high-temperature indicators. If the part has special requirements, you can then consider other refractory on request.
Q:What are the advantages of refractory material?
Jingute WHL type, GDS type
Q:What is the limit of fireproof rolling shutter?
Fire proof door can be divided into Serie A, B and C in terms of fire endurance limit, fire resisting limit are not should be less than 1.20h, 0.90h and 0.60h. Set firewall has difficult sites can use fire shutter fire partition separating, when the back fire surface temperature rise refractory limit determination conditions of fire shutter, the fire resistant limit not less than 3H; when employed does not include back fire surface temperature rise do fireproof limit determination conditions of fireproof rolling curtain, on both sides of the shutter should be set up a separate closed type automatic water spraying system protection, sprinkler system continuation of time should not be less than three hours.
Q:How much is the duration of fire resistance of the porous brick shale?
It depends on its formula since the highest temperature varies from formula. For example, the temperature of common bricks is 900℃, if the lime in it accounts for most part, then the temperature could reach 1050℃; if coal ash accounts for over 40%--50%, then the temperature could amount 1050℃--1150℃, I hope my answer will help you a lot.
Q:Can anyone tell me what is the material of which the mould for refractory is made?
I can make the mould and give you a discount. If necessary, you can contact me at 261240643 (qq).
